Don'tDetroyOnLoad | issue

Hi, I have a player who die when he hit something and persist while reloading the level : using System.Collections; using System.Collections.Generic; using UnityEngine;

public class killer : MonoBehaviour {

 public Rigidbody2D collider2;
 public player script;
 public SpriteRenderer spriteRenderer;
 public Sprite sprite;
 public GameObject GO;
 public bool IsDead;// if already dead

 // Use this for initialization
 void Start () {
     
 }

 void Awake()
 {
     GameObject[] objs = GameObject.FindGameObjectsWithTag("Player");

     

     DontDestroyOnLoad(this.gameObject);
 }
 
 private void OnTriggerEnter2D(Collider2D collision)
 {

     script.enabled = false;
     spriteRenderer.sprite = sprite;
     collider2.constraints = RigidbodyConstraints2D.None;
     IsDead = true;
   
     Application.LoadLevelAsync(Application.loadedLevelName);
     
 }

 }

And a camera who follow him on the x axis

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class cameraplane : MonoBehaviour {

 public Transform transformcam;
 public Transform transformplane;
 public float smooth;
 public float offset;
 // Use this for initialization
 void Start () {
     
 }
 
 // Update is called once per frame
 void Update () {

   // the following mechanic
     transformcam.position = new Vector3(Mathf.Lerp(transformcam.position.x, transformplane.position.x + offset, Time.deltaTime * smooth), 4.5f ,-10);
 }
 }

I want the camera to follow ONLY the one who isn't killed. Please HEEEEEEEEEEEEEEEEEEEEEEEEEEEEEELP
